all of these behaviors would have some gameplay ramifications for sneaking past entities, and could also make them less predictable in a good way
certain entities could stop their usual patrol to do stuff like:
- mess with an interactive prop, like a piano, one of the entities could even be found playing a piano surprisingly well, but will slam the keys if they hear the player and revert back to normal, could raise some questions about the nature of these entities
- have stand-offs with other entities similar to animals, either resulting in a quick pointless scuffle or going their separate ways
- bang their head on a wall repeatedly, making a fairly loud noise that could also unsettle players
- mess with a piece of loot like a toy, maybe a valuable piece of loot, they could drop this if startled, creating a huge risk/reward thing
